Abstract

The invention discloses an in-situ remediation method and system suitable for a petroleum hydrocarbon contaminated site, and relates to the technical field of petroleum hydrocarbon contaminated site remediation. An in-situ remediation method suitable for a petroleum hydrocarbon polluted site comprises the steps that underground water is extracted, and the water level of the underground water is reduced to be below soil of a pollution source area; heating the soil in the pollution source area to volatilize petroleum hydrocarbon in the soil; discharging petroleum hydrocarbon gas volatilized from the soil in the pollution source area; and injecting a repairing agent into the underground water in the pollution plume area. The in-situ remediation system suitable for the petroleum hydrocarbon contaminated site adopts the in-situ remediation method. The problems that a petroleum hydrocarbon polluted site is difficult to repair, energy consumption is large, and cost is high can be solved.

Description

technical field [0001] The application belongs to the technical field of remediation of petroleum hydrocarbon-contaminated sites, and specifically relates to an in-situ remediation method and system suitable for petroleum hydrocarbon-contaminated sites. Background technique [0002] Petroleum hydrocarbon contaminated sites are one of the typical types of contaminated sites. In the long-term large-scale production process of oil mining and processing enterprises, the running, escaping, dripping, and leaking of oil products have seriously polluted the surrounding soil. With the leaching of atmospheric rainfall, the oil gradually migrates downwards, enters the groundwater, causes groundwater pollution, and spreads downstream along the groundwater, forming a pollution plume, resulting in the expansion of the polluted area, thus causing serious harm to the safety of drinking water for residents. [0003] Of course, the remediation modes of petroleum hydrocarbon-contaminated site...
